The display shows HI for humidity, and the unit may run continuously.

Safety: Unplug the unit if you need to access the sensor.

Steps:

• Ventilate room: Open windows or use additional ventilation to reduce extreme humidity.
• Inspect humidity sensor: Locate the sensor behind the front grille. Ensure it is not wet or covered in condensation. Allow it to dry completely.
• Clean sensor area: Gently clean dust from the sensor housing with a soft brush.
• Replace sensor: If HI persists in normal conditions, replace the Sencor humidity sensor module.

Tip: Avoid placing the unit directly next to sources of steam (showers, kettles) which can saturate the sensor.
